What is a flattened sac that reduces friction between adjacent structures during joint activity called?.
Bursae are small fluid-filled sacs lined by a synovial membrane that reduces friction between adjacent structures during joint activity.
What is synovial fluid?It is also called a joint fluid which is thick and located in between the joints. This fluid at the end of the bone reduces friction on the movement of joints.
Regular exercise, a healthy diet, and nutritional supplements increase synovial fluid and reduce joint pain and inflammation.
Bursae provide a cushion between bones and tendons around a joint. It reduces tension and wear and tear at points of friction and allows the free movement of joints. It reduces friction by separating the adjacent structures, preventing them from rubbing against each other.
It is present in large joints such as in the shoulders (ball and socket joint), Elbows , Hips, and Knees.

There are 32 people that are homozygous for this allele in the population.
The Hardy-Weinberg equation states that p + q = 1 thus the sum of allele frequencies for all the alleles at the locus must be 1. Additionally, the Hardy-Weinberg equation is written as follows: p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is the population's frequency of the "a" allele.
The frequency of the homozygous genotype AA is represented by p2, the homozygous genotype AA is represented by q2, and the heterozygous genotype Aa is represented by 2pq in the equation.
Here, q = 0.2. In light of this, p = "1- q = 1 - 0.2 = 0.8.

Steroid hormone are hormone whose receptor will be inside the cell and Protein hormones have their receptor on the cell membrane
Contrary to steroid hormones, which are lipid in composition and can easily enter the cell, proteinaceous signaling molecules must have their receptors anchored in the plasma membrane since proteins cannot cross the membrane. The receptor for protein hormones is membrane-associated and embedded in the plasma membrane of the cell's surface. When a hormone interacts with a receptor, a series of secondary effects are frequently triggered in the cell's cytoplasm.
These effects can include the phosphorylation or dephosphorylation of numerous other cytoplasmic proteins, modifications to ion channel permeability, or elevated levels of intracellular molecules that may serve as secondary messengers. Target cells include steroid hormone receptors on their plasma membrane as well as in their cytoplasm and nucleus. They are typically nuclear or cytoplasmic intracellular receptors that start signal transduction for steroid hormones and cause changes in gene expression over the course of hours to days.

Answer:
There are multiple lines of evidence that provide support for common ancestry and evolution; this would be homologous features of anatomy and embryology and fossil records.
In comparative anatomy, there are many similarities between species because all life is related. Homology is similarities seen because of the ancestry of features or genes in an organism. Similarities can show descent from common ancestors and similarities can be seen in body structures, development, and DNA. Homologous structures are similar traits found in two different species that are the result of having a common ancestor. These structures are similar but may have different functions. An example of this might be the homologous structures in the limbs of humans, cats, whales, and birds. And then there are analogous structures, which similarly is that the structure of different species are similar because the trait is advantageous, not because they are related. An example of this is sharks and dolphins having similar fins. Along with anatomy is Embryology. Different species can have similar embryos because they come from a common ancestor. They may start with the same developmental plan but change drastically as they grow up. An example of this is seen in the early stages of development between fish and chicken embryos.
Next up, the fossil record provides evidence that supports common ancestry and evolution. The fossil record provides us with visual evidence for evolution. The fossil record directly allows us to pinpoint if there are any similar structures amongst organisms and see if there are any vestigial structures from ancestors that remain in organisms that still roam today. The fossil record depicts evolutionary change over the past four billion years, which can be seen through transitional forms, increasing complexity of life, and geographical distribution. Transitional forms are fossils that show intermediate states between an ancestral species and its evolutionary descendants. Increasing complexity is seen as life on earth becomes more complex. That and geographic distribution which has been studied closely and found that the continents have moved over time and that the fossil record reflects this movement. Fossils of different animals can be found on different continents around the world due to continental drift.

Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef. This has something to do with durion
The sharp increase in water temperature due to global warming drives zooxanthellae death. Corals lose their symbiotic algae and suffer bleaching due to the lack of photosynthetic organisms that provide them with color.
What is the algae-coral relationship?Corals are naturally translucid or white organisms. However, they look brightly colored because they host symbionts with colorful photosynthetic pigments.
Corals can host different organisms that live on and among them, giving place to amazing ecosystems.
The photosynthetic unicellular microalgae zooxanthellae are symbionts to the coral.
Corals provide shelter and protection to the algae, and nutrients like carbon, phosphorous, and nitrogen.Algae provide photosynthetic products like oxygen and sugars, and also give color to the corals.This symbiotic relationship allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.
Global warming increases water temperature significantly, which makes the bond between algae and coral break because of algae death. The lack of algae means an increase in coral bleaching since there are no photosynthetic organisms that provide them with color. Besides, the absence of algae means no availability of photosynthetic products.

Inadequate sunlight prevents coral reefs from surviving below the euphotic zone.
The majority of coral reefs are found nearby in shallow water. Due of this, they are particularly susceptible to the negative consequences of human activity, both directly via the exploitation of reef resources and indirectly through the effects of nearby human activities on land and in the coastal zone. The social, cultural, and economic fabric of local coastal communities is intricately intertwined with many of the human activities that harm coral reefs.
Numerous local risks to coral reefs exist, such as:
Physical harm or devastation caused by recreational overuse, coastal development, dredging, quarrying, harmful fishing methods and equipment, boat anchors and groundings, etc (touching or removing corals).

if extinctions are generally a result of changes in the environment that a species is unable to adapt to, what do you think this indicates about the 5 previous mass extinctions and the 6th one occurring now? how long does it typically take for biodiversity to "recover" after a mass extinction?
Answer:
This indicates that extinctions can be both naturally-caused, such as by collapse in food chains due to a large meteorite striking the Earth, and human-caused, including habitat destruction, overharvesting, introductions of invasive species, climate change, and emerging diseases. Because much of the current environmental change caused by human activities is dramatic and sudden, many species may not be able to move or put in the time to avoid extinction. And, the recovery of biodiversity from previous mass extinctions took about 10 million years. The recovery from the present mass exitinction could take just as long-- 500,000 human generations.
